For me, the Billion 7800 seems to offer exactly what I need - wired Ethernet connectivity, a built-in PPPoE EWAN interface as well as an ADSL one, enabling me to use ADSL to the Internet until I get an FTTC setup. Then there's also an ability to set the line's SNR when using it in ADSL mode. In my case I'm on a long, noisy line, so that feature will be all but essential to keep the ADSL connection stable.
I'm wondering if any of you would know the answer to these queries, though:
1) With the 7800, is there any way, through its web interface, of knowing whether the ADSL line is in Fast Mode status or instead Interleaved status? I normally have to have my line set by my ISP to Interleaved, but am now wondering, in changing from my current router to this one, if I'll have any way of confirming that. Thus far, I've used the utility DMT to show this status. However, DMT can't be used with the Billion 7800. I might add that there have been several instances over recent years where changes in my ISP's network have left my connection in Fast mode rather than Interleaved, and were it not for me using DMT I'd have never been in a position each time to request them to set it back to Interleaved.
2) The spaldwick website (www.spaldwick.com/broadband/billion-7800n) gives some guidance on how to adjust the line's target SNR. However, the settings given in the spaldwick tables assume that the user always wants to tweak for a faster sync speed. But what if you want a slower sync speed, and therefore a higher SNR? Does anyone know the values you'd need to insert to go from these target SNRs?:
6dB to 9dB
6dB to 12dB
6dB to 15dB
9dB to 12dB
9dB to 15dB
12dB to 15dB
3) The 7800(N) is IPv6-ready, but is it worth using this at present? It 's been my understanding that not all browsers and not all ISPs can deliver IPv6. Is it best to stick with IPv4 for now?
